Cookies and storage
Last updated 2 October 2026
This site uses no advertising cookies and no third-party tracking. Here is everything it stores in your browser.
| Name | Type | What it's for | How long |
|---|---|---|---|
cf.sid | Session storage | A random number that lets us count one visit as one visit. Never sent as it is: it is scrambled with a daily-changing key before anything is kept. | Until you close the tab |
cf.acq | Session storage | Where this visit came from (the referring site's host name, campaign tags, first page), so every page in the visit is credited to it. | Until you close the tab |
optout | Cookie | Set only if you opt out of counting on the privacy page. Tells our tracker and our server to ignore this browser. | 5 years, or until you opt back in |
Counting needs no consent in the UK, because nothing identifying is kept and you can opt out. It is still storage on your device, which is why it is listed here.
Cloudflare, which hosts this site, may set a strictly necessary security cookie if it needs to check that traffic is from a person and not a bot.
